Vyatta is bringing innovation and affordability to the networking industry by delivering advanced routing and security in a software-based network OS that scales from the branch office to the service provider edge. Vyatta has decoupled networking software from proprietary hardware allowing users to leverage the price and performance advantages of standard x86-based hardware and components as well as Citrix XenServer and VMWare virtual or cloud environments.

In this tutorial brezular shows us how to install Vyatta 6.1 Core LiveCD on Qemu image and run it from GNS3.

GNS3 qemuwrapper always changes MAC address of presented NIC during the boot of Qemu instance. Vyatta is programmed to save MAC address of existing ethernet interfaces. If MAC address of particular NIC is changed (by GNS3 qemuwrapper) Vyatta preserves the interface with old MAC and create new interface with new MAC.

Each time Qemu instace is restarted the number of interfaces doubled.

These are my steps how to solve it (it must be a better solution but I didn’t find any with Google search):

Check Kvm option only if your processor supports hardware virtualization. Check Kqemu option only if it is installed and running. If you are not sure with these options let them unchecked otherwise Qemu will be not started.

You need also set Qemu general settings like path to qemu, qemu-img and qemuwrapper.

- Edit-> Preferences-> Qemu-> General Settings
